In a normal situation, the patient would have had the cup pulled out of his hand. However, the patient, Fred Aryee, did not have his right arm; he lost it in a storm at sea.
How is this possible? When Mr. Aryee lost his arm in 1983, he should not have any feelings after its loss. Yet in amputees, this condition, known as phantom limbs, is all too common. Oftentimes, the feelings that occur are simply ones of normal perception, but often, they are very painful, resulting in another condition called phantom pain.

SO WHAT IS A PHANTOM LIMB? Sometimes referred to as "stump hallucination": it is the subjective sensation, not arising from an external stimulus, that an amputated limb is still present.
